What is Acetoin CAS 513-86-0?
Acetoin CAS 513-86-0 is a naturally occurring organic compound produced through microbial fermentation in dairy products, wines, fruits, vegetables, and other foods, where it contributes to characteristic buttery and creamy aromas; commercially, it is synthesized (often from diacetyl reduction or fermentation) and supplied as a liquid (sometimes dimerizing to crystalline form) for widespread use as a flavoring agent (FEMA 2008) and fragrance ingredient.

Features
- Natural Biosynthesis Role: Arises naturally via fermentation by bacteria in foods like butter, cheese, yogurt, wine, coffee, cocoa, and fruits, providing authentic dairy and fermented notes.
- Milder Than Diacetyl: Offers a softer, less sharp, and less volatile buttery profile compared to diacetyl, making it gentler and more pleasant at higher dilutions.
- High Impact at Low Levels: Delivers strong creamy-buttery effects even in trace amounts (aroma noticeable at 1%, taste at 10 ppm), allowing efficient use without overpowering.
- Versatile Blending: Miscible with water, alcohols, propylene glycol, glycerine, and common flavor materials, integrating seamlessly into diverse formulations.
- Sweet Creamy Enhancement: Boosts perceived sweetness, mouthfeel, and roundness while adding subtle caramelic, dairy, and fatty nuances for balanced flavor depth.
Applications
- Dairy Flavorings: Essential for butter, cream, milk, yogurt, cheese (including cheddar and blue), and imitation dairy products to impart rich, fresh buttery and creamy notes.
- Baked Goods & Confectionery: Incorporated in cakes, cookies, frostings, hard/soft candies, chocolates, and puddings for enhanced buttery richness and mouthfeel.
- Fruit & Berry Profiles: Rounds out strawberry, apricot, peach, pineapple, and tropical fruit flavors with subtle creamy-buttery facets for natural complexity.
- Savory & Meat Flavors: Adds depth to ham, meat products, gravies, soups, snack foods, and seasonings with buttery undertones in savory contexts.
- Beverages & Alcoholic Drinks: Used in nonalcoholic beverages, fruit juices, alcoholic beverages (beer, wine, spirits), and coffees to provide creamy lift and authenticity.
